To a@ 'inkom it may conceive.' f

Be it known that l, As'rnnr W. WH'An'roN,

e citizen of the United States, and a resi'- dent of Churchville, in the county of Bucks find Statewf Pennsylvania, have invented .en improvement in-Automobile Buiiers, ci'

which the following is a specification.

My invention relates to buiers for automobiles and other vehicles and it has for its object to provide a simplel and novel construction of bufiery which is eiiicient for its urpose and which may be cheaply manto ectured andreedily and economically installed. rihe invention resides in the combination and arrangement of parts es hereinafter fully described and claimed und as which l have illustrated one convenient form of embodiment thereof. i

In,the drawing: f f

Fig. 1 is a to plan view of a bui'er construction embo ying my invention and in which is shown in top planend portions of the opposite sides of an automobile chassis or frame upon which the buffer is su ported; and

ig. 2 is a viewin sectional side elevation taken on theline 2-2of Fig. 1.

Referring to the drawing: 1 designates the 'opposite side members of a chassis or frame .of an automobile or other like struc ture having the usual knubend portions 2 to which one end of the springs 2L at the opposite'sides .of the structure are secured by means of bolts 3 which extend through horizontal holes through said knubs.

i designates a buffer bar supported in split bearing sleeves 5 upon the outer ends of the outwardly and upwardly extending arms 6 of levers 7 which are also provided with arms 8 which extend upwardly in a substantially vertical direction, as shown. The buiier bar 4 is clamped and held. in the bee-ring sleeves 5 by lmeans ci clamping bolts 8B. These lever'share pivoted upon the bolts 3 at points' substantially tio-incident with the epexes ot' the ngles between the arms 6 and 8. The upwardly extending arms are provided with openings 9 through which the outer ends of horizontally extending shits 10 extend. The seid bolts also extend through openings in the outwardly extending portions of lugs 12 which are secured to the outer sides of the side members 1 of the automobile or other vehiole frame. The lugs 12 are secured to the said side members l by means of bolts 13,

as shown.

Sleeves 15 rubber or'other suitable" resilient material are mounted upon the bolts 10 between the outwardly extending Y portions oi' the lugs 12 and the upwardly extending arms 8 ot the levers 7. The'erms 8 andv the sleeves 15 are retainedfupon the lbolts lhylnieens of'clamping and binding 'nuts 16 `-which ure retained in place by lock nuts 17. ly vscrewing these nuts tightly against the outer sides of the arms 8 the latter are clamped firmly egainstrthe outer ends oi the sleeves 15 'so as to compress the 1 latter'and hold the same under such tension as may bedeemed desirable.` illustrated in the accompanying drawing in It will be notedv that' the openings 9 are n of slightly 'greater diameter than the i diameter of the bolts 10 whereby in oase the buffe l pivotal 'ement of the levers 7 `will not be too greatly hindered or opposed;

lt will bessen that by reasono the arrangement. es shown, in which the bilder bar 4 is mounted upon the arms 6 which are nite long as eompared with -the arms -8 t e said bar may be moved through considerable distance in case or' collision without the necessity ci. an extensive movement of the .arms S. By reason of the fact that the bilder bar et may be permitted to move through an arcof relatively great length in case of collision the presence of said buier bar aords s greater actoro safety than would be present with the said bar confined to a shorter end more limited movement. cident to a collision would be spread over n greater period of time and would be gradually absorbed by the vehicle structure upon which the louder is mounted.

'Having thus described my invention, what I claim and desire to secure by Letters Patentis:

1 In a buffer for vehicles, the combination of levers having forwardly extending arms und upwardly and vertically extending arrns, the latter having horizontal openings therethrough, a' buii'er bar sup )er 4 should strike an obstruction In other words, the shock in- 5 portions of the said vehicle structure to which the said bolts are connected, and means in .engagement with the outer ends of said bolts for clamping the said sleeves between the said arms and the said portion of the vehicle structure.

2. In a buffer for vehicles, the combination of a chassis having oppositely disposed side members, each of which is provided with an outwardly extending lug having a horizontal opening therethrough,

levers having outwardly and upwardly extending arms and also having vertically and upwardly extending arms, the latter having horizontal openings extending there- 2o through, a buiier barpsecured to the outer ends of the said outwardly extending arms, means for pivotally connecting the said levers at points substantially co-incident .fwith the apexes of the angles between the arms thereof to the ends of the side members of the said chassis, bolts extending through the openings in the said lugs and in the said vertically extending arms, re-

silient members mounted upon said bolts and situated between. the said lugs and the said vertically extending arms, and means for clamping the said resilient members between the said lugs and said arms.

3. Ina buier for automobiles, the combination of the opposite side members of a chassis, which side members are provided with outwardly extending lugs adjacent the .ends thereof, said lugs having horizontal openings therethrough, a bell crank lever pivoted to an end of each of said side members adjacent said lugs, one arm of each of said levers extending outwardly and upwardly and another arm extending upwardly and vertically, each of said upwardly andvertically extending arms being provided with .a horizontal opening therethrough, a buffer bar secured to the outer ends of the first named arms, pivot bolts for connecting the said bell crank levers to the ends of said side members, said pivot bolts having pivotal connection with the said levers at the angles between the arms thereof, bolts extending through the openings in said lugs and the said vertically and upwardly extending arms, rubber sleeves mounted upon said vbolts and situated intermediate the said lugsand the said vertically and upwardly extending arms, and clamping means upon the outer ends of said bolts for clamping the said arms against the outer ends of said sleeves for compressing the same between the said arms and the saidlugs, substantially as described.

In testimony that l claim the foregoing as my invention, l have hereunto signed my name this 27th day of February, A. l).
